194 MINNESOTA STATE HORTICULTURAL SOCIETY. 



In our nursery we have not far from 100 varieties of root grafts put 

 in in the spring of '92 and '93, and about thirty varieties are different 

 from anj^ in the orchard. We design to secure scions of every seed- 

 ling variety that originates in the Northwest that shows any evi- 

 dence of becoming desirable for growing in any section of the state, 

 and put in rootgrafts of them, from five to twenty of each kind. The 

 intention is to set two or more trees of each varietj'^ in the trial 

 orchard, and dispose of the best of the remainder, except such as are 

 received under restrictions, where we can keep track of them. The 

 number of seedlings so far started is about fifty varieties, about 

 thirty of which were put in last spring. The grafts set in 1892 nearly 

 all lived and generally made a heavy growth, and last winter discol- 

 ored the tips of many varieties so that it was necessary to cut them 

 back considerably. Varieties not injured, or the least injured, were 

 Oldenberg, Okobena, Daisy, Good Peasant, North Star, Zuzofif, Hi- 

 bernal, Golden Reinette,Ostrekoff, Im, Patten's Greening, Charlamoff ' 

 Borovinska and five seedlings from Blue Earth county (three of 

 these are double hybrids), and Murph5^'s Greening from Wisconsin. 

 Several varieties of native plums are being propagated by root 

 grafting. 



At the request of Prof. S. B. Green we tried the sand cherry seed- 

 lings as stock for Desotas with most satisfactory results. A much 

 larger per cent, lived than where plum stocks were used and have 

 made fully as good a growth. 



MONTEVIDEO EXPERIMENT STATION. 



LYCURGUS R. MOYER, SUPT, 



The past season was a very trying one at this station. A very wet 

 spring was followed by a protracted drought, during which many 

 of the newly set trees died; a few survived and will be reported on 

 hereafter. Among these are Ribes Alpinum, Ptelia trifoliata, Phel- 

 lodendron amurensis, Siberian alinond, Caragana variagata, Ber- 

 beris thunbergii, Elaeagnus argentea, Siberian arbor vitae, Acer 

 ginnala, Schwedler's maple, besides several varieties of plums and 

 Russian apples. The narrow-leaved cotton wood (Populus angusti' 

 folia) died, much to iny regret. Its native range at the foot of the 

 Rocky Mountains would seem to indicate that it ought to succeed 

 here. 



Fraxitius. It having been my opinion for some time that the ash 

 trees native to this part of the state are mostly green ash (Fraxinus 

 viridis), I sent to Douglas for the true white ash (Fraxinus Ameri- 

 cana) and shall test the two side by side. White ash trees, probably 

 true, from Mr. Dartt, are doing well. Another ash, bought from a 

 Wisconsin nvirsery as white ash, is qvxite tender. It probably is a 

 European species. 



Populus. Among the Russian poplars, Populus certinensis is 

 the most promising. Populus laurifolia is also doing well. Popu- 

 lus Siberica pyramidalis is badly infested with a scale insect and is 

 not growing any. Populus wabski, or 23 Riga, grows rai)idly when 

 young, but the branches are very crooked and the central shoot
